CHARLES J. CARROLL, OF BALTIMORE, MARYLAND, ASSIGNOR OF TWO- THIRDS TO DAVID STEWART AND WlLLlAM ASHTON, OF SAME PLACE.

CASH-REGISTER.

`plECIFICATION forming part of Letters Patent No. 522,823, dated July 10, 1894.

Application filed December 1, 1893. Serial No. 492,440. (No model.)

' o a/ZZ whom t may concern.-

le it known that l, CHARLES J. CARROLL, a citizen of the United States, and a resident of the city of Baltimorain the State of Maryland, have invented certain new and useful Improvements in Cash-Registers, of which the following is a specication.

My invention relates to a cash register deslgned for the purpose of keeping an accurate record of money paid out or paid in to a cash drawer.

The general combination of my machine is one which opens the cash drawer, throws up a tablet corresponding to an amount of money to be paid in or taken out, as the case may be, and makes a register of the tablet'thrown upon a device in the mechanism, thus indieating the amounts putin or taken out of the cash drawer. Each key has aseparate register and the reading of all of the registers together will show at the end of any period just what the contents of the drawer ought to be or exactly how much has been withdrawn.

ln the drawings, Figure l'is avertical section of my machine taken through the line4 --co in Fig. 2. Fig. 2 is a front elevation of the interior of the machine showing certain parts 1n section, taken through the line y-y of Fig. 1. Fig. 3 is a perspective view of one of the key levers and its tablet mechanism. Fig. t 1s a vertical section of one of the registermg tubes containing balls and the stop device by which the balls are retained or released. Fig. 5 is a horizontal section of the registering tube through the line z-e'. Fig. 6 1s one of the balls enlarged.

Referring to Fig. l, 1 is the case of the machlne.

2 is a cash drawer sliding in the lower portion of the case l.

3 is a spring behind the cash drawer and compressed when the drawer is fully in.

4 1s a keeper secured to the back of the drawer and withwhich the latch 5 engages to hold the drawer while shut and prevent it belng opened without the operation of one of the keys of the register.

extending forward through the frame of the machine and provided on their upturned ends with finger buttons for striking. The interior ends of the levers extend back toward the rear of the machine and are marked 8-8.

9 is a spring secured to the frame of the machine below and to the under side of the key levers ou the interior end of the fulcrum 7 s0 that the interior end of the levers is maintained in a depressed condition as shown in Fig. 1.

l0 is a rest consisting of a suitable support bar covered with rubber or other material upon which the ends 8-8 of the key levers rest.

11 and 12 are two bars secured in the sides of the frame of the machine and crossing it from side to side immediately above one another and perforated with a series of holes. Within these holes reciprocate the rods 13--13-l3, on the upper ends of which above the plate 12 are the tablets 14.-'-14 .-14 upon which are painted or stamped in some suitable manner numbers corresponding to the numbers stamped upon the keys G-6. The rods 13-13-13 are similar in number to the key levers and are each mounted in the same plane as one of the key levers so that the lower end of the rod 13 rests upon the top of the key lever near its, extremity 8.

15-15 are two bell crank levers pivoted upon the shaft 16 which is mounted in brackets 17,*-17 in the back of the machine.

18 is a coil spring coiled upon the shaft 1G and arranged to press the upper end of the bell crank levers 15-15 forward and the lower one down.

19 is a bar secured in the ends of the lower arms of the bell crank levers 15-15, and 2O is a bar secured in the extremities of the u pper arms'of the said bell crank levers.

21 is a rod connected to the latch 5 and provided with a slotted eye 22 on its upper end which surrounds the bary 19. Said rod 2l when lifted by the bar 19 and the bell crank levers 15-15 will release the catch 4i andthe cash drawer 2 and permit it to be driven out by the spring 3.

The normal position of the bell crank levers 15--15 under the influence of the spring 18 is to cause the bar 2O to press upon the back of the vertical rodslS-l. The slotted eye 22 on the upper end of the rod 2l will allow thc latch 5 to be pushed up and fall back into the keeper et when the cash drawer is closed without moving the bell cranks l5-l5.

213-2l are lugs secured to the rods l3-l3 and provided on their rear laces with inclined surfaces.

2l is a gong secured to the side of the interior ot the box and is a hammer secured to the upperextremityof the bellcrank lever l5 and in position to strike the gong when that lever is released and allowed to fly forward.

G-ti are a series of tubes secured to the interior el the box at two points 27 and 2S. 'lliese tubes are split dowii the front so that the interior ot the tube is visible and may be graduated either on the surface of the tubes or by thc location of graduated scales or strips of suitable material between the tubes. rlhe upper ends ot' the tubes are open and the lower ends are partially closed by means of a stop device 2O which consists of a piece of spring metal bent in the form ol' a hook and extending across or partially across the bottom of the tube, thus retaining the contents ot` the tube in position while the stop device is across the lower end of the tube. The stop hoek 29 is provided on its lower snrface with a projecting lug` 30 which engages a lug 3l. onthc uppersnrfaee of thekeylevcr. 'lhe motion of the key lever will move the stop device 29 back and vforth across the end ol the tube 2G and cause it to close or open the same with the motion of the lever. The lower end et the tube 2G is cut away at the back as is shown in Fig. 4 so that the front portion of the tube extends down near to the surface of the key levers. The tubes 2G are lilled with balls of any suitable material and of a size about filling the tube, being oi' unilorin size the graduatiens on the surface of the tubes can be arranged to indicate the number of balls contained in the tube.

rlhc end of the tube 2G eut away to give place i'or the stop hook 29 i'orins a bearing` stop for the hook 2!) and also extends down l'ar enough toward the top et the key lever 0 so as to permit a ball to rest below the stop hook 2.() on the top of the key lever and yet be held thereon by the downwardly extending end S2 of the tube 2G. lt will thus be seen that when the key lever G is depressed the ball resting upon the top of the lever will roll down the lever, fall oft of it and drop into thc box 33 immediately below.

3-1- is a stop on the top or" the lever adapted to prevent the ball from rolling forward to the slot in the front plate 35 of the machine through which the key levers pass and be coming jammed therein. The ball must roll oil. the top et the lever when it reaches the stop 3ft and l'all into the box 3S. The box 323 as shown in liig. may be divided into a series el.' compartments one corresponding to each tube, so that the balls released from each tube will tall into a particular compartment provided for it in the drawer; thus the number of balls in each compartment can be used for the purpose of checking the register on the tubes.

3G is a pin passed through a portion ot the frame of the machine and entering a hole in the `front end of the drawer so as to locleit. This pin is only accessible from the interior of the machine.

It will be noticed from the foregoing description that the ball is dropped with the down stroke of the key but the register is made with the up stroke.

The operation ot the device is as follows: lVhen a key lever is depressed a ball is dropped into the drawer and the stop 29 comes forward and closes the end et the tube 2G, corresponding to the key operation and prevents the rest of the balls l'rom falling out. The rod 13 does not reach the key so that thc dropping of the ball is the only work of the lever during the first portion ell its stroke. As the rear end ot the key lever rises it will strike the lower end of the tablet rod and lilt it, as it rises the lug 23 with its beveled rear surface will press upon the bar 2O and push. it back tar enough to allow the lug to pass when the barO will fall back below the lug 23 and hold it up so as to expose the tablet lit in the window 37 on the top of the machine. As the end S of the key lever continues to rise it will strike the bar lt) in the lower arm of the bell crank lever l5 and raise it, throw the bar 20 back and release allot the tablets which may be up and allow them to fall cre cept the one corresponding to the key op erated. As the bar lt) is raised it will pull up the latch 5, by red 2l and eye 22, and release the cash drawer which will be forced open by the spring As the key lever descends the bar 2O of the bell crank will fall against the rods l3-l3 bel'ore the lug` 23 reaches it and said lng and its rod and tablet will be sustained by the bar 2O until it is thrown back by the operation of some other key. As thc upper arm of bell crank lever l5 comes for ward the hammer 25 will strike and ring 'the gong 2- As the keylever continues to descend the lug 3l will recede and stop 25) be withdrawn from the lower end of the tube 2G, permitting one ball to fall upon the lever t3 where it will be held in place by the projecting end 32 of the tube 2G. The bars l0 and lll. lorin the lower and upper stops of the key levers.

My machine is simple in construction and makes a register ot` each key operated upon the 'upward movement of the lever.

Having thus described my invention, what l claim, and desire te secure by Letters Pat ent, is

l. In a cash register the combination ol' a series of key levers, a series of tubes containing counters, one tube located immediately above cach lever, cach tube provided with a stop on its lower end operated bythe key lever and held normally open and a number of counters Ain cach tube falling therein. by

2. In a cash register the combination of a series of key levers,a series of tubes containing counters which fall therein by gravity, one tube located immediately above each lever and a stop, said stop consisting of a spring bent under the tube and engaged by the key lever whereby it is operated to close the tube as the lever descends and open it when it ascends.

3. In a cash register the combination of a series of key levers, a series of tubes containing counters which fall therein by gravity, each tube located above one of the keys, each key being provided with a receptacle for a counter and a stop located upon the end of each tube and operated by the key lever to open the tube and discharge a counter into the receptacle of the key lever on the recoil of the key, substantially as described.

4. In a cash register the combination of a series of keys/each provided with a counter receptacle and a series of tubes one located immediately above each key in which are contained a number of counters falling therein by gravity, each tube being provided with a stop adapted to close its lower end,the stop and operated by the key lever to open the tube and discharge a counter into the key receptacle on the recoil of the key, and close the tube on the operation of the key, the key receptacle adapted to discharge its counter upon the operation of the key.
